I think it was probably somebody with a similar motive to Timothy McVeigh, or that guy who bombed the Olympics because we were too tolerant of homosexuality or something.
Can anyone remember any of these nuts doing anything during the Bush administration? (9/11 falls into a different category, I'm more referring to homegrown nuts.) They seemed relatively quiet then. It seems as though whenever there's a Democratic administration, these people come out of the woodwork.
